Description

本発明は、内燃機関と少なくとも一つの電気機械とを有し、且つ車両のリヤアクスルの駆動用トランスミッションを有するハイブリッド車に関し、ここで内燃機関及び一つの電気機械は、トランスミッションの共通の入力シャフトに対応している。   The present invention relates to a hybrid vehicle having an internal combustion engine and at least one electric machine and having a transmission for driving a rear axle of the vehicle, wherein the internal combustion engine and one electric machine correspond to a common input shaft of the transmission. doing.
前記種類のハイブリッド車は、パラレルハイブリッド車である。前記種類のハイブリッド車の場合、内燃機関と電気機械とが共通のドライブトレインにおいて作動する。従って、少なくとも1つの運転状態で、前記両ドライブの力又はトルクは同時に利用可能となる。   The type of hybrid vehicle is a parallel hybrid vehicle. In the case of the kind of hybrid vehicle, the internal combustion engine and the electric machine operate in a common drive train. Therefore, the forces or torques of both drives can be used simultaneously in at least one operating state.
冒頭に記載した種類のハイブリッド車は、(特許文献1)により公知である。前記ハイブリッド車では、内燃機関、電気機械及びトランスミッションが車両方向に、すなわち縦置きに搭載される。ここで内燃機関は電気機械の前に配置され、電気機械はトランスミッションの前に配置される。前記アセンブリは、この縦置きの配置のために、リヤアクスルから前方に展開する車両の長手方向の広がりに極めて大きい構造的スペースを必要とする。前記車両には、車両のフロントアクスルのホイールを駆動する別の電気機械が提供される。   A hybrid vehicle of the type described at the beginning is known from US Pat. In the hybrid vehicle, the internal combustion engine, the electric machine, and the transmission are mounted in the vehicle direction, that is, vertically. Here, the internal combustion engine is arranged in front of the electric machine, and the electric machine is arranged in front of the transmission. The assembly requires a very large structural space for the longitudinal extent of the vehicle that unfolds forward from the rear axle because of this vertical arrangement. The vehicle is provided with another electric machine that drives the wheel of the front axle of the vehicle.
(特許文献2)は、ハイブリッド車について記載している。前記ハイブリッド車では、2つのホイールを有するアクスルがドライブトレインに対応して設けられている。このドライブトレインは前記アクスルと平行に、すなわち走行方向に対して横置きに配置される。前記ドライブトレインは、内燃機関、電気機械及びトランスミッションにより形成される。電気機械はエネルギー変換器を介してメインバッテリに接続される。従って前記ハイブリッド車はパラレルハイブリッド車としても形成される。   (Patent Document 2) describes a hybrid vehicle. In the hybrid vehicle, an axle having two wheels is provided corresponding to the drive train. The drive train is arranged parallel to the axle, that is, horizontally with respect to the traveling direction. The drive train is formed by an internal combustion engine, an electric machine, and a transmission. The electric machine is connected to the main battery via an energy converter. Therefore, the hybrid vehicle is also formed as a parallel hybrid vehicle.
産業用トラックの形態をとるハイブリッド車において、走行方向に対して横置きに配置されるドライブはまた、(特許文献3)からも公知である。このドライブアセンブリは、車両のフロントアクスルとリヤアクスルとの間に配置される。メインバッテリは、ドライブアセンブリの後ろ、すなわち前記ドライブアセンブリとリヤアクスルとの間に位置決めされる。   In a hybrid vehicle in the form of an industrial truck, a drive arranged laterally with respect to the traveling direction is also known from (Patent Document 3). The drive assembly is disposed between the front axle and the rear axle of the vehicle. The main battery is positioned behind the drive assembly, i.e. between the drive assembly and the rear axle.

本発明の目的は、車両の構造的スペースの最適利用によりハイブリッドドライブの高度な電化が可能となるように、冒頭に記載した種類のハイブリッド車をさらに発展させることである。   The object of the present invention is to further develop a hybrid vehicle of the type described at the beginning so that the hybrid drive can be highly electrified by optimal use of the structural space of the vehicle.
この目的は、内燃機関と、前記一つの電気機械と、電気機械用メインバッテリ又は内燃機関用タンクとが、車両の後部領域において走行方向に対して横置きに配置され、電気機械パワーは内燃機関のパワーより大きいことで達成される。   The object is to arrange the internal combustion engine, the one electric machine, the main battery for the electric machine or the tank for the internal combustion engine in a transverse direction with respect to the traveling direction in the rear region of the vehicle, and the electric machine power is Achieved by being greater than the power of.
ハイブリッド車は、特にスポーツカーである。   Hybrid vehicles are in particular sports cars.
ドライブトレインを横置きに配置することにより、特に、大きい内燃機関を有する公知のリヤエンジンスポーツカーとの関連で、後端領域に比較的大きい構造的空きスペースが生じる。ここで、前記構造的空きスペースは、比較的大型の電気メインバッテリに利用するか、又はメインバッテリが車両の前端に配置される場合には、タンクに利用することができる。このハイブリッド車は電気機械パワーが内燃機関のパワーより大きくなるよう設計されているため、電気機械と内燃機関とで構成されるユニットを、極めてコンパクトな構造のユニットとなるように構成することができる。従ってハイブリッド車、特に通常大排気量の6気筒又は8気筒エンジンにより駆動されるハイブリッドスポーツカーにおいて、例えば、代わりに小型の内燃機関、例えば3気筒エンジン又はコンパクトな4気筒エンジンを使用することが考えられ得る。一つの電気機械は、このようにして自動車の後端領域に得られた構造的スペースに配置される。   The lateral arrangement of the drive train creates a relatively large structural space in the rear end region, particularly in the context of known rear engine sports cars having large internal combustion engines. Here, the structural empty space can be used for a relatively large electric main battery, or can be used for a tank when the main battery is arranged at the front end of the vehicle. Since this hybrid vehicle is designed so that the electric machine power is larger than the power of the internal combustion engine, the unit composed of the electric machine and the internal combustion engine can be configured to be a unit with an extremely compact structure. . Therefore, for example, in a hybrid vehicle, particularly a hybrid sports car driven by a 6-cylinder or 8-cylinder engine with a large displacement, for example, a small internal combustion engine such as a 3-cylinder engine or a compact 4-cylinder engine may be used instead. Can be. An electric machine is arranged in the structural space thus obtained in the rear end region of the vehicle.
従って、前輪駆動量産車両の、又は量産車両製造セットの、大幅に安価な上に低パワーで動く従来の内燃機関ドライブトレインに頼ることが可能である。   Thus, it is possible to rely on conventional internal combustion engine drivetrains that operate at low power while being significantly cheaper in front-wheel drive mass production vehicles or mass production vehicle production sets.
内燃機関、又は一般に横置き搭載物は、水平に配置され得る。スポーツカーに典型的にみられるような低い重心位置は、このようにして維持することができる。この水平配置はまた、横置き搭載物の上に追加的な構造的スペースももたらす。基本的には、内燃機関又は横置き搭載物を、前記水平配置から外れる配置で位置決めすることも可能である。例えば、横置き搭載物を垂直配置で提供してもよい。搭載物の姿勢が斜めに傾いた配置、すなわちエンジンがホイールの接地面に平行な平面に水平に配置されるのでなく、前記平面に対し鋭角をなす平面に配置されることも考え得る。   The internal combustion engine, or generally the horizontal mounting, can be arranged horizontally. A low center of gravity position typically found in sports cars can be maintained in this way. This horizontal arrangement also provides additional structural space above the horizontal mounting. Basically, it is also possible to position the internal combustion engine or the horizontally mounted object in an arrangement that deviates from the horizontal arrangement. For example, a horizontally mounted item may be provided in a vertical arrangement. It is also conceivable that the mounted posture is inclined obliquely, that is, the engine is not disposed horizontally on a plane parallel to the ground contact surface of the wheel, but is disposed on a plane that forms an acute angle with the plane.
本発明の好ましい改良例では、車両のフロントアクスル駆動用の別の電気機械が車両の前部領域に配置されることが提供される。このハイブリッド車は、特に、リヤアクスル用のハイブリッドドライブとフロントアクスル用の完全に電気式のドライブとを有する全輪駆動車両の形態である。   In a preferred refinement of the invention, it is provided that another electric machine for driving the front axle of the vehicle is arranged in the front region of the vehicle. This hybrid vehicle is in particular in the form of an all-wheel drive vehicle having a hybrid drive for the rear axle and a fully electric drive for the front axle.
重量配分、効率及びトラクションの理由から、別の電気機械はフロントアクスルの前に配置することが、特に有利であると考えられる。   For reasons of weight distribution, efficiency and traction, it may be particularly advantageous to place another electric machine in front of the front axle.
車両は、別の電気機械用のメインバッテリを有する。メインバッテリは、好ましくは、別の電気機械と、さらに車両のリヤアクスルの領域に配置される電気機械との両方に割り当てられる。   The vehicle has a main battery for another electric machine. The main battery is preferably allocated both to another electric machine and also to an electric machine located in the area of the vehicle's rear axle.
メインバッテリは、例えば車両のリヤアクスルの領域に配置される。ここで、前記メインバッテリは特に、リヤアクスルの前、且つ内燃機関の前に配置される。或いはメインバッテリは車両の前端に配置されてもよい。   The main battery is disposed in the region of the rear axle of the vehicle, for example. Here, in particular, the main battery is arranged in front of the rear axle and in front of the internal combustion engine. Alternatively, the main battery may be disposed at the front end of the vehicle.
内燃機関の運転用の燃料タンクは、車両の前端において別の電気機械の上に配置されるか、又は車両の後部領域において内燃機関の前に配置される。   A fuel tank for the operation of the internal combustion engine is arranged on another electric machine at the front end of the vehicle or in front of the internal combustion engine in the rear region of the vehicle.
メインバッテリは、好ましくは、固定電源供給ネットワークへの接続部を用いて充電することができる(プラグインハイブリッド)。   The main battery can preferably be charged using a connection to a fixed power supply network (plug-in hybrid).
従って本発明は、その改良例を含め、量産ドライブトレインを使用して製造することのできるハイブリッド車、特にハイブリッドスポーツカーを提案する。これは、具体的にハイブリッド化されたスポーツカーの場合、タンク及び排気系統を有する内燃機関の他に、電気ドライブ、メインバッテリ及び充電ユニットも狭い構造的スペースに収容する必要があることから生じる、構造的スペースが大幅に不足するという問題を解決する。このハイブリッド車には高度な搭載電気パワーが提供されるため、従来の方法で駆動されてきた車両に関連する駆動力の欠点を生じることなしに、内燃機関のサイズを小さくすることが可能になる。ここでは、前輪駆動量産車両の、又は量産車両製造セットの、大幅に安価でいて低パワーで動く従来の内燃機関ドライブトレインに頼ることが可能である。例えば、従来より大排気量気筒タイプのエンジンにより駆動されてきたスポーツカーの場合、このハイブリッド駆動型であれば、小型の量産車両ドライブトレインに変更し、そのパワー不足を、このようにして得られた構造的スペースに高出力の電気機械を用いることにより補償することが可能である。ドライブトレインの前に搭載スペースが得られたことで、リヤアクスルの前に、大型のメインバッテリに十分なスペースが提供され、従って車両の長い航続距離要件を実現し得る。タンクは車両の前端に、別の電気機械の上に配置することができる。タンクは、同じ航続距離を維持しながらも、従来の車両のタンクより小さい寸法とすることができる。この配置によって、車両の前端及び車両の後端の荷物室容積を実質的に維持することができる。衝突時に最も重要な構成要素、具体的にメインバッテリ及び燃料タンクは、即時変形範囲の外側に位置している。ドライブコンセプト全体を、既存の量産車両をベースとして、対応するボディシェルの改良を伴い安価に実現することができる。   Accordingly, the present invention proposes a hybrid vehicle, particularly a hybrid sports car, which can be manufactured using a mass-produced drive train, including an improved example thereof. This arises from the fact that in the case of a specifically hybrid sports car, in addition to the internal combustion engine having a tank and an exhaust system, the electric drive, the main battery and the charging unit must also be housed in a narrow structural space, Solves the problem of a significant lack of structural space. This hybrid vehicle is provided with a high degree of on-board electrical power, which allows the size of the internal combustion engine to be reduced without the disadvantages of driving forces associated with vehicles that have been driven in the conventional manner. . Here, it is possible to rely on a conventional internal combustion engine drive train of a front-wheel drive mass production vehicle or a mass production vehicle production set that is significantly cheaper and operates at low power. For example, in the case of a sports car that has been conventionally driven by a large displacement cylinder type engine, if it is this hybrid drive type, it can be changed to a small mass production vehicle drive train and the lack of power can be obtained in this way. It is possible to compensate by using a high power electrical machine in the structural space. Having the mounting space in front of the drive train provides enough space for the large main battery before the rear axle, thus enabling long cruising requirements of the vehicle. The tank can be placed at the front end of the vehicle, on another electric machine. The tank may be smaller than a conventional vehicle tank while maintaining the same cruising distance. With this arrangement, it is possible to substantially maintain the luggage compartment volume at the front end of the vehicle and the rear end of the vehicle. The most important components in the event of a collision, specifically the main battery and the fuel tank, are located outside the immediate deformation range. The entire drive concept can be realized at low cost with the improvement of the corresponding body shell, based on the existing mass production vehicle.
本発明のさらなる特徴が、従属項、添付の図面及びその図面に示される好ましい例示的実施形態の説明より明らかになる。但し本発明は、前述の例示的実施形態に限定されるものではない。   Further features of the present invention will become apparent from the dependent claims, the accompanying drawings and the description of the preferred exemplary embodiments shown in the drawings. However, the present invention is not limited to the exemplary embodiments described above.
スポーツカーの形態である本発明に係るハイブリッド車を、上から見たときの概略図で示す。The hybrid vehicle which concerns on this invention which is a form of a sports car is shown with the schematic when it sees from the top. 後端領域及び車両の乗員室に属するフロアアセンブリについて、ハイブリッド車の車体の三次元図を示す。The three-dimensional figure of the vehicle body of a hybrid vehicle is shown about the floor assembly which belongs to a rear-end area | region and a passenger compartment of a vehicle.
図1は、内燃機関2と、電気機械3と、車両1のリヤアクスル5の駆動用トランスミッション4とを有するハイブリッド車1を示す。ここで、内燃機関2及び電気機械3は、トランスミッションの共通の入力シャフト6に対応して設けられている。入力シャフト6は電気機械3を貫通して延在する。入力シャフト6は、クラッチ7を用いて内燃機関2のクランクシャフト8に接続することができる。トランスミッション4はディファレンシャル9を介してリヤアクスル5に接続される。リヤアクスル5は、ハイブリッド車1の右ホイール10及び左ホイール11に対応している。   FIG. 1 shows a hybrid vehicle 1 having an internal combustion engine 2, an electric machine 3, and a drive transmission 4 for a rear axle 5 of the vehicle 1. Here, the internal combustion engine 2 and the electric machine 3 are provided corresponding to the common input shaft 6 of the transmission. The input shaft 6 extends through the electric machine 3. The input shaft 6 can be connected to the crankshaft 8 of the internal combustion engine 2 using a clutch 7. The transmission 4 is connected to the rear axle 5 via a differential 9. The rear axle 5 corresponds to the right wheel 10 and the left wheel 11 of the hybrid vehicle 1.
フロントアクスル12は、操縦可能ホイール13及び操縦可能ホイール14に対応している。フロントアクスル12の前に、別の電気機械15が搭載される。前記別の電気機械15は、クラッチ16及びトランスミッション17によってフロントアクスル12に非ポジティブロック式に接続することができる。電気機械15の上にタンク18が配置される。   The front axle 12 corresponds to the steerable wheel 13 and the steerable wheel 14. Another electric machine 15 is mounted in front of the front axle 12. Said further electric machine 15 can be connected non-positively to the front axle 12 by means of a clutch 16 and a transmission 17. A tank 18 is disposed on the electric machine 15.
この車両には、車両1のリヤアクスル5の領域に、メインバッテリ19が走行方向に対して横置きに搭載される。この場合、メインバッテリ19はリヤアクスル5の前に配置される。   In this vehicle, a main battery 19 is mounted horizontally in the traveling direction in the region of the rear axle 5 of the vehicle 1. In this case, the main battery 19 is disposed in front of the rear axle 5.
ハイブリッド車では、例えば、第1の電気機械の最大パワーが約90kW、特に90kWであり、且つ第2の電気機械の最大パワーが約90kW、特に90kWであり、さらには内燃機関の最大パワーが約160kW、特に162kWであることがある。そのようなレベルのパワーは、例えば1.4リットルの排気量を有する4気筒内燃機関により発生する。この内燃機関用の燃料を収容する、フロントアクスルの領域、すなわち1つの電気機械の領域に配置されるタンクは、例えば約45リットルのタンク容量を有する。   In a hybrid vehicle, for example, the maximum power of the first electric machine is about 90 kW, in particular 90 kW, the maximum power of the second electric machine is about 90 kW, in particular 90 kW, and further the maximum power of the internal combustion engine is about It may be 160 kW, especially 162 kW. Such a level of power is generated, for example, by a four-cylinder internal combustion engine having a displacement of 1.4 liters. A tank that accommodates the fuel for the internal combustion engine and is disposed in the region of the front axle, that is, the region of one electric machine, has a tank capacity of, for example, about 45 liters.
従って電気機械パワー、すなわち2つの電気機械のパワーは、内燃機関のパワーより大きい。   The electric machine power, ie the power of the two electric machines, is therefore greater than the power of the internal combustion engine.
明瞭性を高めるために選択される選択図に関わらず、内燃機関2は垂直に配置されるのではなく、むしろ好ましくは略水平に配置される。従って、内燃機関2と電気機械3とトランスミッション4とから形成されるドライブトレインについては、スポーツカーにおいて典型的である低い重心位置が維持される。内燃機関2及び電気機械3の寸法により、内燃機関2が占める構造的スペースは、電気機械3が占める構造的スペースより小さい。ドライブトレインを横置きに配置すると、後端領域に比較的大きい構造的空きスペースが得られる。前記構造的スペースは、比較的大型の電気メインバッテリ19に利用される。   Regardless of the selection chosen to increase clarity, the internal combustion engine 2 is not arranged vertically, but is preferably arranged substantially horizontally. Therefore, the drive train formed by the internal combustion engine 2, the electric machine 3, and the transmission 4 maintains a low center of gravity position that is typical in sports cars. Due to the dimensions of the internal combustion engine 2 and the electric machine 3, the structural space occupied by the internal combustion engine 2 is smaller than the structural space occupied by the electric machine 3. When the drive train is placed horizontally, a relatively large structural space is obtained in the rear end region. The structural space is used for a relatively large electric main battery 19.
図2は、ハイブリッド車1の車体20の部分的領域を示す。この図は、乗員室に属するフロアアセンブリ21を示し、またハイブリッド車1の後端車体領域22も示す。前記領域から、内燃機関2と電気機械3とトランスミッション4とを含む、ハイブリッド車1において後方奥深くに配置される構成の前に、十分な構造的空きスペース23があることが分かる。この構造的空きスペース23の領域に、横置きされるメインバッテリ19を配置することができる。前記メインバッテリは図示しない。基本的には、前記領域にメインバッテリを配置する代わりに、そこにタンクを配置することが可能である。この場合、フロントアクスルの領域には、タンクを提供する代わりに、メインバッテリが配置される。   FIG. 2 shows a partial region of the vehicle body 20 of the hybrid vehicle 1. This figure shows the floor assembly 21 belonging to the passenger compartment, and also shows the rear end vehicle body region 22 of the hybrid vehicle 1. From the region, it can be seen that there is sufficient structural empty space 23 before the configuration including the internal combustion engine 2, the electric machine 3, and the transmission 4, which is arranged deeply in the rear in the hybrid vehicle 1. The main battery 19 placed horizontally can be disposed in the area of the structural empty space 23. The main battery is not shown. Basically, instead of placing the main battery in the area, it is possible to place a tank there. In this case, instead of providing a tank, a main battery is arranged in the area of the front axle.
ハイブリッド車1は、固定電源供給ネットワーク(プラグイン)への接続部(図示せず)をさらに有する。   The hybrid vehicle 1 further has a connection part (not shown) to a fixed power supply network (plug-in).
